These targets are regularly used for embedded applications for portions of code where the Advanced SIMD registers may not be preserved, such as interrupt handlers.
Disabling the use of SIMD registers for memset/memcpy operations by default ensures that code which doesn't overtly perform FPU or SIMD operations won't end up using those registers unintentially.
